TZK50 Jumper Settings
========================================================================
The TZK50 is a SCSI controller for a TK50 tape (CompacTape (tm))
drive. It is normally found along with a conventional TK50 tape drive
in a TK50Z-FA or -GA tape drive subsystem.
The TK50Z-FA was supplied with MicroVAX and VAXstation 2000 systems,
and its TZK50 was set to SCSI ID 1 by jumpers.
The TK50Z-GA was supplied with later systems (such as MicroVAX and
VAstation 3100 systems), and offered a DIP switch pack on its rear panel
for setting the SCSI ID.
